Gets the job done

This bladder is simple and easy enough to use. I took it on a hike/climb and it performed just as I thought it would. I was a little nervous taking it out anywhere near some of the sharp granite we were hiking on as it seemed pretty thin. Another concern was the opening at the top. It was locked down with a clam that seemed to slip off with the bounce of my pack. Overall I think it's great but may look into something with a tougher skin in the future.

Don't let the thickness or clarity of the bladder fool anyone. This is made of puncture resistant material. My experience has been positive in regards to the durability of the Big Zip as well as other Platy products.
